Excerpt from Journal of Entomology and Zoology, 1936, Vol. 14 Instructors and Purchasing Agents who are on the lookout for newer and better sources for preserved material and slides will be glad to learn that we are better than ever equipped to supply high quality material for the following sciences. Botany A set of microscopical slides of general morphology, which has been declared to be of better quality and selection than similar sets put out by any other commercial firm in the United States. Zoology A very complete line of preserved material, excellent microscopical slides and living material of many forms. Parasitology Microscopical slides of Trypanosoma gambiense, Plasmodium vivax, Treponema pallida in tissue, Entamoeba histolytica in sections of the human colon, Necator Americanus and other economically important parasites. Also preserved material. Embryology Serial sections of 10 millimeter pig embryos, in which a very high standard of technique has been attained. Owing to the method evolved, we are able to quote very attractive prices on these. Serial sections and whole mounts of Chick embryos. Preserved pig embryos and chick stages. Also slides and preserved material illustrating the development of the Starfish, Sea Urchin, Lobster Barnacle and certain other invertebrates. Skeletal Preparations Excellent preparations of many representative forms. Cartilagenous skeletons are mounted on glass background in liquid. Ligamentous skeletons of bony forms are prepared in such a manner that all parts are properly shown in their manural relations, with the use of visible artificial supports. Our Guarantee Should either preserved material or slides prove unsatisfactory, advise us and upon return of same we will refund both purchase price and transportation costs.
